Comparison of Neutrophil-Lymphocyte Ratio Values and C-reactive Protein Levels in Sufferers of Systemic Inflammatory Response Syndrome with Positive and Negative Blood Culture

Introduction

Systemic Inflammatory Response Syndrome (SIRS) is a nonspecific reaction that can be caused by infection, inflammation, or a combination of both factors. It is a complex condition that poses a significant challenge for clinicians in detecting bacteremia in SIRS patients. In this context, the ratio of the number of neutrophils to lymphocytes (NLCR) and C-Reactive Protein (CRP) levels can be used to quickly predict the presence of bacteremia. This study aims to compare the NLCR values and CRP levels in SIRS patients with positive and negative blood culture.

Background

SIRS is a condition characterized by a systemic inflammatory response that can be caused by various factors, including infection, trauma, burns, and severe sepsis. It is a complex condition that requires prompt and accurate diagnosis to prevent serious complications. The detection of bacteremia in SIRS patients is a critical aspect of patient management, as it can lead to sepsis and multiple organ failure if left untreated. The use of biomarkers such as NLCR and CRP can help clinicians in detecting the presence of bacteremia in SIRS patients.

Research Methods

This study was conducted in a cross-sectional design in H. Adam Malik Hospital, Medan, in the Emergency Unit from January to March 2016. Patients who meet the SIRS criteria underwent NLCR, CRP, and blood culture examinations. A total of 48 samples were taken, with 21 (43.75%) of them being men and 27 (56.25%) being women. The study was approved by the Institutional Review Board (IRB) of the hospital, and informed consent was obtained from all participants.

Research Results

The results show a significant difference between the NLCR values of the two groups of patients. NLCR in SIRS patients with positive blood culture is recorded higher than SIRS patients whose blood culture is negative, which is 38.16 versus 34.97 (p = 0.001). In addition, CRP levels also show a significant difference, where CRP levels in SIRS patients with positive blood culture are higher than the negative (5.89 versus 3.15; p = 0.001).

Discussion

NLCR is a simple but effective biomarker for detecting systemic infections in patients who are in critical condition. In this study, there is a significant difference between NLCR values and CRP levels in SIRS patients who have positive and negative blood culture. This shows that these two parameters can function as indicators in assessing the status of infection in patients with SIRS. The use of NLCR and CRP can help clinicians in making appropriate clinical decisions and improve patient management with this serious condition.

The Importance of NLCR and CRP in SIRS Patients

NLCR and CRP are two biomarkers that can be used to detect the presence of bacteremia in SIRS patients. NLCR is a simple and cost-effective biomarker that can be used to quickly predict the presence of bacteremia. CRP is a more sensitive biomarker that can detect the presence of infection even before the onset of symptoms. The use of these biomarkers can help clinicians in making appropriate clinical decisions and improve patient management with this serious condition.

Conclusion and Suggestions

From this study, it can be concluded that there are significant differences in NLCR and CRP between SIRS patients and positive and negative blood culture. Therefore, NLCR and CRP can be used as a useful marker in detecting the presence of bacteremia in SIRS patients. The use of this biomarker can help doctors in making appropriate clinical decisions and improve patient management with this serious condition. Thus, it is important for health institutions to consider the use of NLCR and CRP in their diagnostic protocols, so they can be faster and more accurate in dealing with SIRS patients and prevent more serious complications due to bacteremia.

Limitations of the Study

This study has several limitations. Firstly, the study was conducted in a single hospital, which may limit the generalizability of the results. Secondly, the study only included patients who meet the SIRS criteria, which may not be representative of all patients with SIRS. Finally, the study only used two biomarkers (NLCR and CRP) to detect the presence of bacteremia, which may not be sufficient to detect all cases of bacteremia.

Future Directions

Future studies should aim to validate the results of this study in a larger and more diverse population. Additionally, future studies should aim to explore the use of other biomarkers in detecting the presence of bacteremia in SIRS patients. Finally, future studies should aim to develop a more accurate and sensitive diagnostic protocol for SIRS patients.

Conclusion

In conclusion, this study shows that there are significant differences in NLCR and CRP between SIRS patients and positive and negative blood culture. Therefore, NLCR and CRP can be used as a useful marker in detecting the presence of bacteremia in SIRS patients. The use of this biomarker can help doctors in making appropriate clinical decisions and improve patient management with this serious condition. Thus, it is important for health institutions to consider the use of NLCR and CRP in their diagnostic protocols, so they can be faster and more accurate in dealing with SIRS patients and prevent more serious complications due to bacteremia.
Frequently Asked Questions (FAQs) about Systemic Inflammatory Response Syndrome (SIRS) and the Use of Neutrophil-Lymphocyte Ratio (NLCR) and C-Reactive Protein (CRP) as Biomarkers

Q: What is Systemic Inflammatory Response Syndrome (SIRS)?

A: SIRS is a nonspecific reaction that can be caused by infection, inflammation, or a combination of both factors. It is a complex condition that poses a significant challenge for clinicians in detecting bacteremia in SIRS patients.

Q: What is the Neutrophil-Lymphocyte Ratio (NLCR)?

A: NLCR is a simple but effective biomarker for detecting systemic infections in patients who are in critical condition. It is calculated by dividing the number of neutrophils by the number of lymphocytes in a patient's blood sample.

Q: What is C-Reactive Protein (CRP)?

A: CRP is a more sensitive biomarker that can detect the presence of infection even before the onset of symptoms. It is a protein that is produced by the liver in response to inflammation.

Q: How can NLCR and CRP be used to detect bacteremia in SIRS patients?

A: NLCR and CRP can be used as indicators in assessing the status of infection in patients with SIRS. Elevated levels of NLCR and CRP can indicate the presence of bacteremia, which can lead to sepsis and multiple organ failure if left untreated.

Q: What are the advantages of using NLCR and CRP as biomarkers?

A: The use of NLCR and CRP as biomarkers has several advantages, including:

They are simple and cost-effective to measure
